The Hot Chocolate Run will also extend the closure north of the Battery Street Tunnel
March 4 update: The viaduct inspection is now complete and the structure is open to traffic for the rest of the weekend.
Drivers should be aware that the annual Hot Chocolate 15k/5k Run will close SR 99/Aurora Avenue North Sunday morning, March 5 from approximately 6 a.m. to noon.
It’s March and that means it’s time for a weekend-long inspection of the State Route 99 Alaskan Way Viaduct. Every March and October, the Washington State Department of Transportation closes SR 99 through Seattle so engineers can conduct a thorough inspection and make sure the viaduct remains safe
for everyday driving.
On Saturday, March 4 and Sunday, March 5, the viaduct will close in both directions between South Spokane Street and the north end of the Battery Street Tunnel.
On Sunday, March 5, the annual Hot Chocolate Run
will also extend the closure north of the Battery Street Tunnel.
Drivers through Seattle should plan ahead and be prepared for additional congestion. The Seattle Department of Transportation will post updated information on their traveler information webpage.
Additionally, drivers can check WSDOT’s travel tools
for information about traffic in the Puget Sound region.
